It's a very good novel to pass time, the world building are good. Also this novel can only be read from chapter 1-1481, after that, the contents of the chapters will again start in chapter 1

Basically a pokemon collection type harem, all of his wives are basically vases with no contributions to the mc, besides their presence which helps mc collect points, the female leads have only been helpful to the mc when they still have no relationship to each other, as for the side characters they have no brain, they basically take anything at face value and didn't think much about any thing weird as long as the mc is involved. Maybe a decent novel, if you turn off your brain, at least that my opinion on this.
